Abstract

A system and a method for its use are provided to cool a cryotip at the distal end of a probe for a cryosurgical procedure. In particular, the cryotip is cooled by a liquid refrigerant to cryogenic temperatures in order to perform a cryosurgical procedure on biological tissue. The system is closed-loop, and during transit of the liquid refrigerant through the entire system, the liquid refrigerant always remains in a liquid state at a relatively low pressure.
